Tired of throwing away money on batteries that don't seem to last?
We bought 11 different brands of AA batteries and put them in identical flashlights to shed some light on which ones last the longest. We tested major labels, drug store brands, and a few found at the Dollar Store.
We turned the flashlights on and waited.
The first to go were the Panasonic alkalines. They lasted a minute shy of two hours. The Rayovacs that came with the flashlight were next. They only lasted two hours and 15 minutes. The Panasonic Plus gave out at 2:45 and the Evereadys died after three hours and 33 minutes.
The Dollar Store's longest-lasting battery was Sunbeam. These batteries are 25 cents each and lived four and a half hours.
Nine minutes later, Walgreen's batteries went dark — which hurts when you've paid 98 cents for each one.
The Dollar Store batteries were inexpensive, and now we see why. The one ray of light was the Sunbeam brand.
The drug store brands fared much better, but with a price tag around a dollar a battery, they're much more expensive.
CVS batteries outshined many we tested — they clocked in at five hours and nine minutes. But the Energizer you thought would "keep going and going" only lasted two minutes longer than the CVS brand.
And then there were two: Kirkland and Duracell. Both weakened at the same time , but Duracell beat Kirkland by five minutes with a total life span of five hours and 56 minutes.
The copper top came out on top!
Kirkland's price is what sets them apart. They are 27 cents per battery versus 94 cents for the name brands. Would you pay three times as much for a five minute difference?
